I'm using Ubuntu 10.04 LTS
By typing the command:
hostname --fqdn
I get the following
hostname: Name or service not known

How to set the hostname and FQDN on Ubuntu Server 10.04?
View 5 Replies View RelatedWhen I type in "hostname", the result is locahostname and not localhostname.domainname.
For example, if the hostname is zazu and the domain gateway.2wire.net. I need for "hostname" to return zazu.gateway.2wire.net.
I am using the 2wire router. But - there is a dynamic DNS domain that points to the router.
how to set the FQDN properly so that "hostname" returns zazu.pridelands.com
How do i use perl regex to extract the hostname from a FQDN?
I have
Quote:
$host=ganymede.a.linux.com
$host=io.a.linux.com
$host=europa.a.linux.com
i just want the characters which are to the left of the first .(dot) in FQDN name. I could get it using substr and split function,but how do i get it through regex.
I have a network of 2 WinXP machines and one linux box. I have fiddled around with the settings as you do when learning. The network is working. The network neighbourhood on the WinXP machines recognise the linux box and vice versa, (the linux Places|Network recognises the 2 WinXP). I can Ping the linux box using its hostname from a WinXp. But I cannot do the reverse. I get an 'unknown host' response. I can ping the linux to itself using its hostname.

View 5 Replies View RelatedI'm having an issue on two Fedora Core 13 machines where I can ping others by hostname, but the hostname resolution fails whenever I use ssh/scp/vnc/etc. I can still do these things by IP address, just not by hostname. RHEL5.3 machines on the same network with the same configuration do not seem to have this problem.
Here's the not-so-quick-and-dirty description of the situation:
I know that there is a virtual router at 192.168.31.1 and another at 192.168.30.1. I also know that there is another network (let's call it 90.90.90.0) and on that network lies a number of resources. By nature of this configuration, any machine on 90.90.90.0 can be accessed by any 192.168.x.x, but not the other way around. Beyond that is out of my hands and currently out of my scope of knowledge.
I have a dnsmasq server on 90.90.90.10 that operates as a secondary nameserver, another machine out of my sphere of influence is the primary nameserver (90.90.90.31).
The secondary nameserver on 90.90.90.10 holds the hostnames of our development machines. The problem is that in some cases, while I can ping by hostname all day long, services such as ssh, scp, vncviewer, etc all fail to resolve the hostname. In other cases I can do all of these things.
Every machine has an equivalent resolv.conf:
As an example, I will show the output of a handful of my development machines:
I also included columbia as a one-way test -- even though it cannot access 30.x or 31.x, they can access it:
columbia -- physical machine, Red Hat Enterprise 5.3, IP 192.168.100.200
Okay, so here are the various outputs. Remember, nibbler, discovery, and atlantis can ALL:
- Ping by IP address
- Ping by hostname
- ssh, scp, vnc, etc by IP addess
Additionally, the SERVFAIL reply from 90.90.90.31 is expected since my dnsmasq server is on the secondary server.
Note that the only machine that can both ping and ssh/scp/etc by hostname is nibbler, which also happens to be the only one of the three running RHEL5.3 instead of FC13. Other virtual and physical machines running on the 192.168.31.0 and 192.168.30.0 networks (all running RHEL5.3) work just like nibbler does. So the problem seems to only affect machines running FC13.
Final note: selinux is disabled, iptables is disabled, ip6tables is disabled.
Other than that, discovery is a brand-spanking-new install straight off of the FC13 DVD. atlantis has been around longer, but its just a file server so I haven't done anything too crazy to it.
How do I set $HOSTNAME to dynamically update with the hostname that is specified for the ip in DNS?

If I try doing,ping <hostname>then I get the messageping: unknown host <hostname>however, if I doping <hostname>.localthen I get a response back.

View 2 Replies View RelatedI have an ubuntu 10.04 server with hostname "abc.domain.com". However, due to migration, we had to change to hostname to something else, "xyz".
I have done changing /etc/hosts and /etc/hostname and run /etc/init.d/hostname start.
Checking the hostname and all shows it is now using hostsname of xyz. However, email sending out is still using old hostname. We have some scripts that will send out alerts like failed rsync or hdd space full to my email account. But I see the sender is still "root@abc.domain.com".
How do change that to xyz? I am using postfix. I have edited main.cf and restarted postfix but no go.
when I enger hostname -f i get file can not be found I then tried yast lan and get invalid command.So How do I set the FQDN in my centos server?
View 1 Replies View Relatedbrand new install of 10.4 server and I'm having a strange issue. I cannot browse to any website by it's domain name, but I can connect via IP address.
I've been googling around and did the following:
added nameservers to /etc/resolv.conf based on an nslookup from my windows box:
nameserver 71.250.0.12
nameserver 68.237.161.12
I commented out the hosts line in /etc/nsswitch.conf per another site and changed it to: hosts: files dns
I can see other computers on my local network via IP and I can browse to the server's default apache page by it's hostname, so I'm assuming it's something about the server's dns resolution, but I'm not sure of my next step.
I want to install Globus tool kit it says host name is not FQDN(fully qualified domain name) I tried by installing DNS but it doesnt works
I got the configuration. I have posted in following link. I am not able to reply your post i dont know why. [URL]
i have xp and virtual guest centos 5.i install apache, bind, squid and webmin through xp, i can access URL...but when i start my squid, put the ip in the browser proxy settings, when i logon its ip turn to URL...I believe my bind is working. Though theres some little glitch. I dont know where.and i already put my servers bind ip to my winxp primary dns server settings.
View 1 Replies View RelatedI have an RHEL5 server running BIND. I'd like to be able to resolve internal, non-FQDN names such as "wiki" for the company internal wiki. in my named.conf file...Named-checkzone returns no errors, and nslookup works when specifying the server explicitly, but no browser resolves the name when entered in the address line. I know this by no means a standard use of BIND, but I'm sure someone out there's pulled this off. I did see when googling someone suggest "load the root zone (.) as master, and add your "hosts" as TLDs, using CNAMEs", but tried that and probably did it wrong since it didn't work.

I've installed a new copy of Ubuntu 10.10.Now the big question for me is how do we assign hostname to a given ip? I've given the hostname during the server installation and "cat hosts" says "ebox" hostname I'm trying to put on.Also,I modified the network/interfaces to static and assigned proper values.
#hostname returns ipaddr not the hostname. Also nslookup hostname/ipaddr says server can't find ....
So,is installing dns through bind and setting-up the only way to do that?
I am having problem resolving hostname. i had 1 server and its hostname is resolving fine. i purchased 1 vps and its hostname isnt resolving. for server 1 say hostname is server1.domain.com. and for vps i add server2.domain.com. and when i ping my server2.domain.com i get Host Unknown error. do i add Hostname and make it resolve in VPS. i want to use hostname like server2.domain.com.

I admit I am a little green with the "Bourne Again Shell" (Bash), even though I was always not as proficient with the Bourne or Korn shell as with C Shell. From recent research the public sway is to Bash over tcsh. I can see I have been away from Linux/UNIX way to long.

This is to be added to an auto_start shell script start up our application on Linux workstation and servers.
